Colorimetric detection of methionine based on anti-aggregation of gold nanoparticles in the presence of melamine
Sensors and Actuators B: Chemical(2018)
Abstract
•A rapid strategy for colorimetric determination of methionine (Met) using gold nanoparticles (AuNPs) is presented.•This assay was based on anti-aggregation of AuNPs and showed high selectivity and sensitivity.•This assay was applied to detect Met in serum and urine samples.
